Be it known that I, CLAUDE A. Conovnn, a citizen of the United States, and aresident of Newbur h, in the county of Orange and State of ew York, have invented a new and Improved Pencil Sharpener, of which the following is a full, clear, and exact description.

This invention relates to pencil Sharpeners and has for' an object to provide an improved construction wherein an ample cutting surface is presented while the lead of the pencil is protected against breakage.

Another object of the invention is to provide a pencil Sharpener is which the cutting member is arranged ina tube capable oi receiving a pencil retaining fitting.

A further ob'ect of the invention is to provide a pencil Sharpener formed in two principal parts connected together in a suit-v able manner and formed so as to be usable alone or in connection with a supporting tube ln the accompanying drawing-- Figure 1 is a side view with a@ i. broken away disclosing one bo'diment of the invention.

Figure 2 is a plan view of the cutting structure shown in Figure 1.

Figure 3 is an edge view of thestructurs shown in Figure 2.

Figure d is a view similar to Figure 2 but looking at the same `from the opposite side.

Figure 5 is a sectional view through Figure 1 approximately on line 55.

Figure 6 is a sectional. view through the cutter shown in Figure 2 but with the parte welded together.

Fi re 7 is a view similar to Figure t but showing the parte riveted together instead of welded.

Referrin to the accompanyin drawing by numera s, 1 indicates a tube o a proper size to receive the cutt structure 2 as shown in Fi re 2. The tube 1 is provided with a restricted end 3 which may receive a rubber eraser or other implement as desired while the open end is esigned to receive a pencil similar to pencil 4 whenever it is desired to sharpen the same and when the Sharpener is not being used a clip or xture 5 may be inserted into the open end of the-tube. 'The clip 5 is provided with a rounded face 6 designed.to snu ly 1[it the open end of the tube 1 and wit ent namely, a strong,

`rately, or the form shown in Figures gripsor clamping members. 7 and 8 or principal parts, namely, the part or section 9 and the part or section 1G. These parts are identical except that the part or section 10 is cut away at 11 whereby the -shavings may freely escape and the lead of. the* pencil may have Aa free `opening. The respective parts 9 and 10 are made from fiat ieces of metal pressed with tapering portions l2 and 13, portion 12 being outV away to form the opening 11 while one edge of portion 13 is bent slightly inwardly and sharpened at 14 for forming a cutting edge. ln the form of the invention shown in Figures 2 to 5, the plate 15 from which the tapering portion 13 is preedis positioned with the edge in one turned over flange 16 and part of one edge of the turned 4over 'flange 16. The iiange 16 is preferably formed integral with the plate. 17 Jfrom which the pressed out portion 12 is formed, is positioned as shown in Figures d and 5 and acts to hold the two parts or sections 9 and 10 firmly together. lf desired, the parts could be welded, as for instance, alon the line 18 (Fig. 6) or could be spot-weide at diderent places. Also, the parts might be riveted together by suitable rivets 19 as shown in Figure 7. lt will be understood that a large number of other ways could be provided' for seourin these arts together and the same resu ts obtained,

to-properly cut the wood of a pencil and taper the lead without breaking the lead. It will be noted that the cutting edge 1d extends from near the large end 2O of the sections 9 and 10 entirely across the cut- N5 away portion 11 in order that the lead will be properly tapered in addition to properly cutting the wood of the pencil. lf desired, the cutting structure 2 may be used sepasimple structure adapted l at@ 5, u@

or maybe forced into the tube 1 and-'used in connection therewith. When thislatter course is followed, the tube 1 is provided with a slot 21 opposite the cutting edge or knife 14 whereb the parts removed from the pencil may lie freely discharged. The cuttin structure 2-may be held in the tube 1 mere y by friction or may be secured therein by solder or other means as the cutting structure 2 is made from comparatively thin, high grade steel which would ord1- narily be used in a protecting tube similar to tube 1, which tube may be easily mounted on the end of a pencil similar to pencil 4 or may be connected therewiththrough the clip 5.

Other slight changes and modifications might be made without departing from the spirit of the invention provided the cutting "wf structure is formed substantially as shown in Figures 1 to 7 inclusive.

What I claim is 1. A pencil Sharpener comprising, a cut(- ting structure formed with a sharpened o' knife, and a centrally positioned web substantially rectangular, and a tube for receiving said cuttinoestructure, said. web fitting against the W'a s of the tube whereby the cutting structure is properly centered in the tube.

2. A pencil Sharpener comprising a cutting structure formed in two parts, each part being constructed of sheet metal and having a tapering portion arc-shaped in cross section, and a web extending from the edges thereof, and means for securing said We s together, one of said tapering portions belng cut off at the small end While the opposite ta ring portion having one edge separated rom lts web and sharpened, said sharpened edge being bent inwardly to produce a cutting knife.

3. A pencil Sharpener formed in two sections, each section having a tapering semitubular structure, and a web extending from the ed es of said structures, means for securing sa1d Webs together, one of said tapering structures being cut o at theismall end for presenting an opening while the opposite tapering structure is bent inwardly and formed with a cutting edge extending across said opening.
